LABORATORY DIAGNOSIS OF PURULENT INFLAMMATORY DISEASES CAUSED BY STAPHYLOCOCCUS SPP., STREPTOCOCCUS SPP., AND PSEUDOMONAS AERUGINOSA

Purulent inflammatory diseases are commonly caused by pyogenic bacteria such as Staphylococcus spp., Streptococcus spp., and Pseudomonas aeruginosa. These microorganisms are responsible for a wide spectrum of infections, including skin and soft tissue infections, postoperative wound complications, abscesses, and systemic infections. Accurate laboratory diagnosis plays a crucial role in identifying the causative agent and selecting appropriate antimicrobial therapy. The diagnostic process involves proper specimen collection, Gram staining, culture on selective and differential media, biochemical identification, and antimicrobial susceptibility testing. Early detection of resistant strains, including MRSA and multidrug-resistant Pseudomonas aeruginosa, is essential for effective treatment and infection control. A comprehensive laboratory approach ensures timely diagnosis, targeted therapy, and prevention of complications.
